Main Uses:1. As a refractory material: Graphite and its products have high temperature resistance and high strength properties. In the metallurgical industry, they are mainly used to manufacture graphite crucibles. In steelmaking, graphite is often used as a protective agent for steel ingots and as a lining for metallurgical furnaces.2. As a conductive material: In the electrical industry, it is used to manufacture electrodes, brushes, carbon rods, carbon tubes, anodes for mercury rectifiers, graphite gaskets, telephone parts, coatings for television picture tubes, etc.3. As a wear-resistant lubricating material: Graphite is often used as a lubricant in the machinery industry. Lubricating oil often cannot be used under high-speed, high-temperature, and high-pressure conditions, while graphite wear-resistant materials can operate at temperatures of 200-2000 ℃ at very high sliding speeds without lubricating oil. Many devices that transport corrosive media widely use graphite materials to make piston cups, sealing rings, and bearings, which do not require the addition of lubricating oil during operation. Graphite emulsion is also an excellent lubricant for many metal processing (wire drawing, pipe drawing) operations.4. Graphite has good chemical stability. After special processing, graphite has the characteristics of corrosion resistance, good thermal conductivity, and low permeability, so it is widely used in the manufacture of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, and pump equipment. It is widely used in the petrochemical, hydrometallurgy, acid-base production, synthetic fiber, and papermaking industries, saving a large amount of metal materials.5. As a casting, sand casting, molding, and high-temperature metallurgical material: Due to the small thermal expansion coefficient of graphite and its ability to withstand rapid cooling and heating changes, it can be used as a casting mold for glassware. After using graphite, ferrous metals obtain castings with precise dimensions and smooth surfaces, resulting in high yield rates. They require little or no processing before use, thus saving a large amount of metal. In the powder metallurgy process for producing cemented carbides, graphite materials are usually used to make molds and crucibles for sintering. Single crystal silicon crystal growth crucibles, zone refining containers, support fixtures, induction heaters, etc., are all made from processed high-purity graphite. In addition, graphite can also be used as graphite heat insulation plates and bases for vacuum smelting, high-temperature resistance furnace tubes, rods, plates, and grid shelves.6. Used in the nuclear energy industry and national defense industry: Graphite has good neutron moderation properties and is used in nuclear reactors. The uranium-graphite reactor is a commonly used type of nuclear reactor. The moderator material in nuclear reactors used for power generation should have a high melting point, stability, and corrosion resistance. Graphite fully meets these requirements. The purity of graphite used in nuclear reactors is very high, and the impurity content should not exceed tens of PPM. In particular, the boron content should be less than 0.5 PPM. In the national defense industry, graphite is also used to manufacture nozzles for solid-fuel rockets, nose cones for missiles, parts for spaceflight equipment, heat insulation materials, and radiation shielding materials.7. Graphite can also prevent boiler scaling. Relevant unit tests have shown that adding a certain amount of graphite powder to the water (approximately 4-5 grams per ton of water) can prevent boiler scaling. In addition, graphite coated on metal chimneys, roofs, bridges, and pipelines can prevent corrosion and rust.8. Graphite can be used as pencil lead, pigments, and polishing agents. After special processing, graphite can be used to make various special materials for relevant industrial sectors.In addition, graphite is also a polishing agent and rust inhibitor for glass and papermaking in light industry, and an indispensable raw material for manufacturing pencils, ink, black paint, ink, and artificial diamonds. It is an excellent energy-saving and environmentally friendly material, and the United States has already used it in car batteries. With the development of modern science and technology and industry, the application fields of graphite are constantly expanding. It has become an important raw material for new composite materials in high-tech fields and plays an important role in the national economy.
